NFT is the abbreviation of English irreplaceable token, that is, heterogeneous pass, that is, irreplaceable pass. This kind of card can represent some uniqueness, and two different cards are irreplaceable. How to understand this substitutability? Substitutability is a relative concept, either in a certain scene or in a certain dimension. For example, the cryptocurrency btc, I take a btc and a btc in your hand is equivalent and replaceable. Another btc won't change anything for you and me. But some things are different. For another example, I have a card signed by Zhang Mingxing, and so do you. These two cards may have the same face value, but the status of this signature in my heart makes me reluctant to exchange it with you. Moreover, some things are irreplaceable by different classifications. For example, when I travel, I like to see the scenery outside the window. My high-speed rail ticket by the window and your ticket in the middle seat are irreplaceable.

NFT can lock ownership through blockchain. Take some non-decentralized digital assets as an example. For example, your WeChat account, QQ account, etc. , they can be deprived. If we use blockchain to manage ownership, we can be more reliable and give corresponding management rights. The ability of transmission and exchange can be obtained after popularization. On the basis of independent control, it is more convenient to certify the transfer of assets. After authentication, assets are easier to authenticate and verify. The authenticity of artworks and collectibles has always been a problem, and generalization can improve this problem. ?

Some NFT standards have been formed in the blockchain ecology. With standards, interoperability can be achieved. The same pass can be managed by different wallets, displayed in different markets and displayed in the virtual world. Standards also enable passes to be tracked, and transactions are recorded in a standard form in any market; Standards can also bring liquidity; Of course, standards are programmable. In short, standards can make NFT more powerful. ?

At the same time, NFT can anchor the concept of goods in the real world, because it has the characteristics of heterogeneity and indivisibility, such as universal tickets, a precious bottle of red wine, uniquely designed jewelry and so on. NFT enables us to authenticate anything of value and track the ownership of this information, thus realizing the intersection of information and value.
